Failover & redundancy setup...

Hi guys,

I work for a wireless ISP. We are in the process of converting our 
network to use DHCP and honestly ISC DHCP works great.

We are setting up a redundant server which I originally planned to use 
anycast to provide easy redundancy. However for failover it requires a 
split or hba command to decide who answers the query which means both 
have to receive it.

This is not much of a problem it is just that our 2 server farms are 
relatively far apart and i was planning to route requests to the closest 
one to minimize latency and only failover to the further server if the 
closer one died.

I am currently using 3.1.1 (latest stable in gentoo's package system) 
and thus far searching through the change logs this behavior hasn't 
changed since.

Thanks in advance for any help provided.
